Lumbar muscle strain, especially repeated lumbar and back sprains, as well as prolonged sitting, standing, exposure to cold, and chill, can all cause lumbar muscle strain. Therefore, it is first necessary to avoid excessive bending and lifting activities, as well as exposure to cold and chill, particularly abnormal bending and lifting activities. Normally, one should squat first, then lift heavier objects and hold them close to the abdomen, which is a more correct posture for lifting things. After injuring the lumbar muscles, it is advisable to persist with local physical therapy daily, such as heat therapy, acupuncture, and physiotherapy, while avoiding cold, chill, prolonged sitting, and standing. One can also take some non-steroidal anti-inflammatory and analgesic drugs orally. During the non-acute phase, when there is no obvious pain in the lumbar muscles, one can try exercises like planking, proper jogging, and pull-ups to enhance the strength of the back and lumbar muscles, which can promote the recovery of tissue damage from lumbar muscle strain and increase its strength.
